The number of bytes for each prefix encoded below. This field can be
anywhere from 4 (shortest prefix) to 32 (full SHA256 hash).
In practice this is almost always 4, except in exceptional circumstances.
The hashes, in binary format, concatenated into one long string. Hashes are
sorted in lexicographic order. For JSON API users, hashes are
base64-encoded.
